Broadband Identification of Battery Electrical Impedance for HEVs [PDF]
IEEE Transactions on Vehicular Technology, 2013 Electrical impedance measurements provide useful information about the characteristics of a Li-ion battery. The classical method of measurement consists of performing electrochemical impedance spectroscopy (EIS) that relies on offline records of the response of the battery to a controlled current or voltage test signal.

Bayesian identification of acoustic impedance in treated ducts [PDF]
The Journal of the Acoustical Society of America, 2015 The noise reduction of a liner placed in the nacelle of a turbofan engine is still difficult to predict due to the lack of knowledge of its acoustic impedance that depends on grazing flow profile, mode order, and sound pressure level. An eduction method, based on a Bayesian approach, is presented here to adjust an impedance model of the liner from ...

Identification of Irradiated Potatoes by Impedance Measurements
Agricultural and Biological Chemistry, 1982 Measuring the impedance was found to be a highly reliable and practical technique for identifying irradiated potatoes. Impedance was measured by puncturing a potato tuber with a steel electrode and passing a 3 ~ 5 mA alternating current through it. Three parameters were determined: Z0/Z180 (impedance ratio at 5 kHz, 0 to 180 seconds after puncturing ...

Online Contact Impedance Identification for Robotic Systems
2008 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2008 In this paper, we study the performance of various algorithms for fast online identification of environment impedance during robotic contact tasks. In particular, we evaluate and compare algorithms with regard to their convergence rate, computational complexity and sensitivity to noise for different environments using a single degree-of-freedom ...

Identification of cracks with non linear impedances [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2003 Summary: We consider the inverse problem of determining a crack submitted to a nonlinear impedance law. Identifiability and local Lipschitz stability results are proved for both the crack and the impedance.
